Why are you likely to have a heart attack shoveling snow?

Question

I’ve always heard/been told to be careful while shoveling snow, that you’re more likely to have a heart attack. Why would I be more likely then as opposed to exerting myself during normal temperatures?

Some people do not exercise whatsoever, and thus their hearts are quite weak. When these people suddenly physically exert themselves by shoveling snow, which is somewhat intensive, their hearts literally cannot handle it.

For people who exercise frequently, this is not an issue and you are not more likely to have a heart attack whole shoveling.
